I To all whom it mag concern:

Be it known that I, Amos Gr. CANBY, a

- citizen of the United States of America, re-

siding at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Ornaments the wing of Fig. 1 adjacent to Fig. 3;

Fig. 4 is a view in transverse section of the wing adjacent thereto in Fig. 1, and

Fig. 5 is a view in section showing the longitudinal curvature ofone of the blades of the device, and indicating the reverse 7 curvature of the other blade in dotted lines.

As herein shown, a spindle 1 is detachably secured in any suitable manner to the cap 2 of an automobile. a thrust bearing for the lip 4; turned out from the lower margin of a blade 5 of suitable sheet material. The latter is slit at intervals along the center and has hinge portions 6 struck up through which the spindle is thrust to steady the blade. The wings of the member 5 are oppositely curved longitudinally as indicated in Fig. 5 and preferably are each concaved or dished transversely, so that they present opposite faces of unequal resistance to the wind and hence cause the device to spin rapidly. The upper marginal portion 7 of each wing may be bent as a flange on the concave face of the wing.

At the upper end portion of the spindle 1 there is a reduced bearing or ournal head 8 over which a lip 9 of an upper blade 10 is secured rotatably by any retaining head such as a ball 11 which is apertured to go on to a still further reduced end portion 12 where it is secured suitably. The hinge portions 13 struck up between transverse slits of the central part of the upper blade 10 form steadying means on the spindle and the A base 3 thereon affords.

wings thereof, "which are oppositely curved longitudinally to cause rotation of the blade in one direction, the blade being 'reversely" disposed to the wings o'f-the member 5, so"

that the blade turns in an opposite direction to the other blade when mo ed through the air orstruck by the wind. I

Suitable ornamentations ofthe wings, as by representations of flags or emblems thereon, cause the device to present a very pleasing appearance, as the device looks the same from all directions, when in motion. By. placing the same design upon the corre-" sponding faces of the wings, as for example,

the British flag on the convexfaces, and

another design, as for example, the French tricolor, upon the concave faces of the wings of a blade, the efiect is of twoflags flying from opposite sides of the spindle, regardless of the point of view.

Obviously, changes in the details of construction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular fornior arrangement of parts.

What I claim is 7 1. An ornament comprising an upright spindle adapted to be secured to the cap of anautomobile radiator, asymmetrically disposed lower blade journaled on the spindle and provided with oppositely extending wings, and an upper blade rotatable'on the spindle and provided with oppositely 6X- tending wings, the wings of the blades being curved to cause the blades to rotate in opposite directions imder the influence of air through which the blades are moved.

I 2. An ornament comprising an upright spindle adapted to be secured to the cap of an automobile radiator, a pair of blades mounted to revolve on the spindle under the influence of air moving past the spindle, each provided with oppositely disposed and convexed wings, corresponding sides of the wings ofthe blade having similar designs wherebythe blades present different designs on the sides of the spindle when the blade is spinning, and the blades being disposed to turn in opposite directions under the in fiuence of air through moved. V g

3. An ornament comprising an upright spindle, a base forming a thrust bearing :on the lower end portion of the spindle, there being a reduced upper portion on the spindle forming an upper thrust bearing, a lower which the blades are 7 blade having oppositely disposed and curved Wings extending in either direction from the medial line thereof, an apertnred lug on the lower margin of the blade engaging over the spindle and riding on the-face of the thrust bearing, hinged portions on the blade formed by transverse slits in the body thereof, curved to form bearings on the spindle, an upper blade having oppositely disposed equal Wings, the curved surfaces ofwhiehare disposed oppositely to the corresponding lower blades whereby the upper bladesrotate in opposite direction to the lower blades,

Copieslofthis patent may be obtained for transverse slits and thrust out and tion of the spind-le and bearing against the upper thrust shoulder formed thereby, and hinged portions in the-blade body formed by bent to engage over the spindle.
